PRESSING MACHINE (SLIDING' HEAD).

Application led February 24, 1926. Serial No. 90,398.

This invention relates to a pressing machine of the type in which anironing head or a large sad iron is movable lengthwise of the buck andalso forwardly and rearwardly over the face of the lbuck and also has amovement toward and from the buck. l't has for its object a particularlysimple, etlicient and easily controlled power mechanism for actuatingthe ironing head lengthwise of 1 the buck and also forwardly andrearwardly.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.- U

In describing this invention reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure 1 is a side elevation, partly 1n Isection, of a machine embodyingmy invention. Figure 2 is a plan view of parts seen in Figure 1.

Figure 3 is a longitudinal sectional view through the motor Ameans forthe swinging carriage.

Fi re 4 is a longitudinal sectional view through one of the manuallyoperable means or valves.

This machine comprises, generally, a buck, an ironing head movabletoward and from the buck, a support for the ironing head including ayokepivoted on a horizontal axis, a swinging carrier pivoted to the yoke ona vert-ical axis, a slide movable toward and fromv the axis of thecarrier and carrying the ironing head at its front end, manuallycontrolled means for moving the yoke to carry the head toward and fromthe buck, and manually controlled power means for moving the carrier andthe slide.

1 designates the buck which may be of any suitable form, size andconstruction, it being mounted upona suitable ,frame 2 or a table 3. onthe frame.

4 is the ironing head.

5 is the yoke for supporting it, the yoke being pivoted at 6 on ahorizontal axis to an upright 7 rising from the frame or a rear leg 8thereof.

9 is the carrier having an upright bearing 10 mounted on a verticalshaft or spin-- dle 11 suitably carried by the yoke 5 in front.

of the axis 6 thereof. A

l2 is a sliding bar movable in a suitable guide 13 in the carrier' 9 andcarrying the ironing head 4 at its front end, the bar 12 being hereshown as connected to a rod 15 which threads vertically through thefront end of the slide 12 and which is connected by a universal joint 16to the ironing head- 4. The threaded rod 15 is turned by means 60 of awrench applied to the upper end thereofl and is held in its adjustedposition by a wheel 17 threading thereon, the wheel serv, ing as a jambnut. The slide 12 moves on suitagole rollers18 and 19 carried by thecar- 05 rier The yoke 5 is actuated either by power or by foot to 'applythe pressure, and in the illustrated embodiment of my invention, theyoke 5 must be preliminarily actuated be- 70 fore the power can beeffectively applied.

The yoke 5 is here. illustrated asinitially actuated to bring the head 4down onto the buck 1 by means of a foot lever 2O pivoted at 21 to theframe and having an arm 22 arranged to hook back of the lower link 23 ofa toggle. The other link 24'of the toggle' is pivoted at 25 to the reararm of the yoke 5. The links 23 and 24 are pivoted together at 26.Obviously by depressing the pedal 9 20` the toggle 23, 24 will bestraightened and hence the head 4 moved down onto the buck 1 or the workthereon. After the head 4 ha's been brought down on the buck 1 heavypressure may be applied by power through a .5 levery 27, pivoted at 21to the 'frame or on the same pivot that the foot lever`^20 is mounted,the power lever having a thrust link 28 pivoted at 29 thereto, whichthrust link coacts with the lower end of the link 24 90 to thrust thelink 24 endwise, when its lower end has been -brought into engagementwith the thrust link 28 by the preliminary closing of the head 4 by thelever 20.. The power lever 27 is actuated by a roller 31 mounted 95 onan eccentric or crank pin 32 carried by a suitable shaft journaled in ahousing 34, the roller coacting'with .a face on the front end of thelever 27. The shaft on which the pin 32 is mounted is actuated from anelectric 100 motor 35y through suitable reduction gearing and a periodicclutch not shown which is manually controlled, that is, the clutch isthrown in by-hand and automatically thrown out when the eccentric 32makes a 105 half revolution. l

The link 28 is held in its angular position relatively to the lever 20in any suitable manner as by a rod 28a pivoted within the rear leg 8 andextending through an 110 opening in the link 28 and having a nut 28b atits rear end. A spring 28c encircles the rod-.between an abutmentthereon and the link 28 and holds the link 28 against the nut. Thisfeature forms no part of this invention.

The throwing of the clutch is controlled by a suitable pedal 36connected by a link 37 to a rock shaft 38 having an arm 39thereon`coacting with the rock arm 40 pivoted at 41 to the clutch housing 34and operating to throw the clutch therein.

' The power mechanism and clutch and its operating mechanism, form nopart of thisinvention and further description is unnecessary to a fullunderstanding thereof. Upon the depression of the lever 36, the

clutch is thrown in'and the eccentric 32 caused to make a halfrevolution to depress the power lever 27 and hence apply power to thehead 4 after the head has been preliminarily closed. To open the press,the lever 36 is depressed again so that the eccentric 32 makes anotherhalf revolution back to the position shown in Figure 1.

The means for actuating the iron 4 lengthwise of the buck or to rightand to the left acts on thev carrier 9 to swing it about the pin 11.This means is here shown as a cylinder 42 having a double acting piston43 therein and piston rods 44 and 45 extending through opposite ends ofthe cylinder and connected to a yoke 46 havingv a rack 47 thereonmeshing with the pinion 48 on the bearing 10 of the carriage 9. Thecylinder 42 has combined intake and exhaust pipes 50 and 51 at each endthereof and the How of air through the pipes 50 and 51 is manupressedair.

ally controlled. Likewise the slide 12 is actuated by a similar cylinder52 carried by the guide 13 of the carriage 9 and having a double actingpiston 53 therein, the rod 54 of which is secured at 55 to the frontend.- of the slide.

A combined intake and exhaustpipe 56 or 57 is connected to each end ofthe cylinder 52. The flow of air through these pipes 56, 57 is alsocontrolled by manual means. The manual control means is the same in allinstances and is as shown in Figure 4 and comprises a valve casing 60having a normally closed spring pressed intake valve 61 and a normallyopened exhaust valve 62 and a combined intake and exhaust pipe 50, 51,56 or 57 between the valves 61, 62. 63 designates the intake pipe from asuitable source of supply of energy as com- 61 and 62 are connected by astem 64 so that they work in unison and this stem is actuated by abutton 65, themotion ofwhich is transfer-red to the stem 64 through asuitable motion, transmitting lever'66. There is a button 65 forcontrolling the opening ot each pipe 50, 51 and a button 65 forcontrolling The intake and exhaust valves the flow 4through each of thepipes 56, 57. All of these buttons are conveniently located on the frontof the machlne, and that for controlling the forward movement run isdesignated 65F, that for controlling the backward movement 65B. Thatforcontrolling the swinging of the lever to the left is designated 65L andthat for controlling the swinging to the right 65,3.

In operation after the head 4 has been brought down on the buck asdescribed, the ironing head 4 can be caused to swing to the left bypressing the button 651, which opens the normally closed intake valve 61in the lett hand pipe 50 and closes the exhaust valve which is normallyopen so that the piston 43 moves to the right causing the rack 47to,move to the right, turning the pinion 48 and hence the carriage 9 ina'clockwise direction or to the left. Depression of the button 65R opensthe valve 61 in the right hand pipe 51 causing the piston 43 to move tothe left and the pinion 48 to move in an anticlock direction. At thesame time or separately either, button 65B' or 65B may be operated tocause the slide 12 to move forward or backward.
